Question

A force of 10N is acting on an area of 2cm square. Find the pressure exerted by the force . If the force is acting perpendicular direction

Answer 1

force = 10N

Area = 2cm^2 = 2/100×100 =2×10^-4 m^2

pressure = F/A

=10/ 2×10^-4N/m^2

=5×10^4pascal

Answer 2

Concept:

Pressure is defined as force applied perpendicular to the surface per unit area which is given by

$P=\frac{F}{A}$ where,

$P$ is the pressure exerted by the force

$F$ is the force applied perpendicular to the surface

$A$ is the area on which force is acting

Given:

Force of $10N$ is acting on area of $2 cm^{2}$.

To Find:

We are asked to find the pressure exerted by the force

Solution:

By considering the given data,

$P=\frac{F}{A}=\frac{10}{2*10^{-4} }$

$P=\frac{5}{10^{-4} } =5*10^{4} N/m^{2}$

Hence the pressure exerted by the force is $5*10^{4}N/m^{2}$
